script.Parent.Touched:connect(function(Part)
    local Human = Part.Parent.Parent.Parent:FindFirstChild("Humanoid")
    if Human and Human.Parent.Name ~= Character.Name then
        Human:TakeDamage(20)

Mouse.KeyDown:connect(onKeyDown)

I'm trying to make it where the player damages other players/npcs when you press the key.
